IMPROVEMENT IN RAILWAY-AXLE-BOX LIDS.

Specification forming part of Letters Patent No. 192,199, dated June 19,1877 application filed May 5, 1877.

To all whom it may concern:

Be it known that we, FRANCIS O. LEwIs GUSTAVUS SUSEMIHL and HERBERTHILLS HEWITT, of Detroit,'in the county of Wayne and State of Michigan,have invented a new and Improved Journal Oil Box Cover for Railway-Cars,of which the following is a specification:

Figure 1 is a vertical longitudinal section on line 00 w in Fig. 2. Fig.2 is a plan view.

Similar letters of reference indicate corresponding parts.

Our invention relates to the covers of journal oil-boxes forrailway-cars; audit consists in a cover or lid having projections formedon its edges that are received by grooves formed 1n flanges that projectfrom the sides of the oil-box.

In the drawing, A is an oil-box, consisting of a single casting havingthe aperture a for receiving the car-axle, and the aperture b forintroducing the journal-box and for oiling. At the sides of the boxflanges or ears B project a small distance beyond the front and abovethe top of the box, and are grooved in their inner surfaces from a pointopposite the lower corners of the aperture b upward and rearward totherear edge of the flange.

The cover (J is provided with projections 0 that are received by thegrooves c in the flanges B. The cover 0 is provided with flanges at itsends, and with acentral longitudinal rib, d, on its outer side, forconvenience in open ing or closing it.

The distance between the truck side iron D and the flanges B is lessthan the distance from the projection c to the edge of the cover, sothat it is impossible to remove the cover so long as the box A is inplace in the truck.

The apertureb is opened by raising the cover 0 until the projections care at the upper end of the grooves, when it is tipped and at the sametime carried so that it lies partly upon the top of the box A. The coveris shut down by reversing this operation; and should the oiler neglectto shut it, the jarring of the car will cause it to tilt and closeitself.

The cover cannot be lost, as it can only be removed from the box byremoving the box from the truck; and it cannot easily be bro ken ordisarran'ged. v

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. The cover 0, having flanged ends and acentral rib, d, and provided with the peojections 0, substantially asand for the purpose herein shown and described.

2. The cover 0, having projections c, in combination with the box A,having formed upon it the grooved ears B, substantially as shown anddescribed.
